To install a transceiver in the QFX Series:
CAUTION: To avoid electrostatic discharge (ESD) damage to the transceiver,
do not touch the connector pins at the end of the transceiver.
Remove the transceiver from its bag.
1.
Check to see whether the transceiver is covered by a rubber safety cap. If it is not,
2.
cover the transceiver with a rubber safety cap.
WARNING: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing a cable. The rubber safety cap keeps the port clean
and prevents accidental exposure to laser light.
If the port in which you want to install the transceiver is covered with a dust cover,
3.
remove the dust cover and save it in case you need to cover the port later.
Using both hands, carefully place the transceiver in the empty port. The connectors
4.
must face the device chassis.
CAUTION: Before you slide the transceiver into the port, ensure that the
transceiver is aligned correctly. Misalignment might cause the pins to
bend, making the transceiver unusable. Note that on QFX5100-48T
devices, the QSFP+ top and bottom ports have the same orientation for
inserting and removing transceivers. On all other QFX Series devices, the
ports are designed belly-to-belly, which requires you to turn the transceiver
over on the bottom port row. See

transceiver.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables
connected to transceivers emit laser light that can damage your eyes.
